BOX-BOARD.

Application filed March 26, 1998.

To all ywhom 'it ymay concern.'

Be it known that I, HENRY L. Enviamos-n, of Indianapolis, county ofiilarion, and State ol' Indiana, have invented a certain new and usefulBox-Ecard g and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the acconuyanyingdrawings, in which lilre numerals refer to like parts.

'lhe object of this inventioii is to provide an imprfrfed box board, orboard made of paper for use in the manufacture of paper boxes.

rFlic chief feature of this invention consists in a box board formed ofa plurality of layers of paper board with reinforcing strips securedbetween said layers. I'lerctofore, reinforcing strips have been securedon the inside or the outside of paper boxes at the corners thereof forrf-iiuforcing the same. In such case it is troublesome and expensive toadd the reinforcing strips to the boxes after they are made and there isleft a roughened or an gular surface on the box along each edge of thereinforcing strips. lilith the box board herein set forth the materialis all ready for making the box without the subsequent addition of thereii'iforcing strips7 as said strips are already in the box board. Afterthe box is formed the surface of the boxes, both on the inside and theoutside, is smooth.

rlhe full nature of this invention will be understood from theaccompanying drawings and the following description and claims. i

In the drawings Figure i is a plan view of the sheet of box board withthe reinforcing strips indicated by dotted lines. Fig. 2 is a transfersesection of the box board on an enlarged scale to show the formationthereof, the same boing centrally broken away. Y F a transverse sectionof the box board after the saine has been bout7 the board beingcentrally broken away.

In the formation of the box board herein shown three layers 10, 11 and1B are united by any suitable uniting` material, as is well known tomanufacturers of box board. The invention need not be limited to boardmade of three layers, as it may be applied to one having two or morelayers.

Specification of Letters Patent.

Patented June 15, 1909.

Serial No. 423,393.

In the formation of the board longitudinally extending reinforcingstrips 15 are inserted between two layers thereof and secured to theadjacent layers by adhesive material in the same manner and at the sametime as the other layers are secured together. These reinforcing stripsare located at predetermined points where it is intended to l score orbend the box board to form the box.

In the case of the board herein shown it is bent longitudinally along ascore line substantially central of the reinforcing strips 15 and thenin forming the box said board is bent at three points to form sides,bottom and top thereof. That is, the portion of the board between thereinforcing strips forms the sides, bottom and top, while the portionoutside of said reinforcing strips may form the ends. At any rate, thereinforcing strips are so located between the layers that when the boardis folded into a box, the reinforcing strips will overlap the corners;In that herein shown and described, the two reinforcing strips overlapthe eight corners of the box that is to be formed. This strengthens andreinforces said corners and yet leaves a box with smooth interior andexterior surfaces and the manufacturer of the boxes is relieved from theexpense and trouble of adding reinforcing strips. 'If his renders saidbox board of great importance in the manufacture of boxes, especially inlargo quantities.

IWhat I claim as my invention and desire to secure by Letters Patent is:

1. A box board formed of a plurality of layers united together, andreinforcing strips at intervals secured within said layers.

2. A box board formed of a 'plurality of rectangular layers unitedtogether, and a reinforcing strip secured Within said layers near cachlateral edge of said board where said board will be bent in forming thebox.

In Witness whereof, I have hereunto affixed my signature in the presenceof the witnesses herein named.

HENRY L. BEVERIDGE.
